GSX1400 rear shock upgrades?

[rewdmc]

The reason I recommended the "ORG" fix was that is NOT an attempt to rebuild the shocks(a job for a pro) but simply refilling the preload adjuster with heavier oil.
The only safety issue is to be sure to have the preload backed RIGHT OFF before starting.
Of course if you are a mechanical two legged disaster with no right to have a spanner in your hand then DO NOT ATTEMPT THIS,stick to crosswords.
I was just trying to help the guy out as he has nothing to loose and everything to gain,if it works then the money he saved could be spent on other bike improvements(pro suspension setup/rider training etc).
I take no responsibility for anyone's mechanical missadventure.

Hey guys, thanks for all the imput to this issue. I have tried the .org shock fix but that didn't work for me and Ive tried to get second hand stuff from the wreckers here and in aussie with no success. Robert Taylor I would very much like the ohlins and thanks for your info but budget and priorities put these out of the picture.
I have settled on a set of Hagon adjustable shocks which have completely changed the bikes handling so am pretty happy with the result, thanks Nic at NV Motorcycles in morrinsville for getting these for me.

I fitted them to my XJR years ago. Good choice.

Out of curiosity, what are your plans for the old shocks?

[ARNIE]

I put them in a box and shoved them on a shelf

So putting heavier weight oil in your shocks is going to do what?

Make anything that was orifice limiting currently, do it at a lower shaft speed.

Still, people used to recommend filling your forks with 50W & adding an inch of preload spacer.


nuthin to lose. cept some skin.

Na, confused me too. The "fix" from that other site, is for the hydrolic preloader only. That system is sealed from the damping fluid, and completely independant.

[F5 Dave]

Ah, ok, didn't want to go to that site unless I caught something. As you were.

Yes, excellent point of generalisation about this age old misconception of filling with heavier oil. A good way to crash when you havent actually identified the real reasons and you've more often than not made the forks lethargic and non responsive.

I think it is better to be totally uninformed than ill informed. And certainly dont take ''advice'' from the ill informed. The same guys are probably also advising how to do ''do it yourself open heart surgery''. After all its posted on the net and everything on the net is authoritative...........and of course even the incorrect stuff is correct. ''Ive done my research on the net'' we all too often hear.

Adding heavy oil and preload spacers to sloppy undersprung forks is something we did in the 70S, when we all knew nothing about suspension. It wasnt a correct solution then and it certainly isnt now.

Frankly the ''she''ll be right'' attitude doesnt wash in this modern world

Did you miss the bit about it being the preload adjuster not the shock oil?

[Kickaha]

Did you miss the bit about it being the preload adjuster not the shock oil?

Did you miss the bit where he's talking about forks?

No, you missed my opening qualifying statement.

Who brought forks into this,for what reason???
The "org'' fix is NOTHING to do with forks.And NOTHING to do with dampening,pre load adjust only.
Find out what people are talking about before you put your 2 cents in.

[F5 Dave]

I did. And I don't answer to you.

Not guilty but it bought up an important point about going too heavy in viscosity. As it is also safety related it is justifiable to talk about. If there is no call to help people from a suspension proffessionals point of view giving free AND SINCERELY INTENDED advice then Ive got plenty of other things to do. As has F5 Dave who most times has something very reasonable to offer.

If a preloader requires heavier oil Id ask why? Is it a ''Heath Robinson'' fix? Cheap fixes usually only deliver a cheap and temporary stalling of the inevitable.
